1 Given that R is between A and X on a segment, draw a picture and write an equation
using the Segment Addition Postulate. Then find AR and RX if AR = 3x,
RX = 4x - 9, and AX = 68.
2.
Given that R is the midpoint of segment AX, write an equation if AR = 3x and
RX = 4x -9. Then find AR, RX, and AX.
3.
The endpoints of a segment are (4,17) and (9,5). Find the length of the segment to
the nearest tenth and then find the coordinates of the midpoint.

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
